BATTERY DRIVING DEVICE, LOAD CONTROL METHOD, INTEGRATED CIRCUIT AND LOAD CONTROL PROGRAM

摘要

The present invention aims to provide a battery-driven device that is capable of extending an operating time of a battery (a secondary battery). A battery control unit 220 included in the battery-driven device of the present invention stores therein one or more voltage thresholds, and detects a sharp voltage drop that occurs immediately after the start of discharging of the battery fully charged, based on the current voltage of the battery and the stored voltage thresholds. On detecting the sharp voltage drop, the battery control unit controls power consumption of the battery to decrease.
